Unusual mastitis pathogens have a mean prevalence of 8 to 25% of microbiological isolates on a specific broth. These germs have their own epidemiological model, which is mostly environmental. For Prototheca, the main risks are water and food sources. In cases of Candida mastitis, we must always evaluate treatment practices for contamination. Other pathogens such as Enterococcus and Klebsiella are closely linked to bedding quality, whereas Listeria is mostly related to ration contamination. Arcanobacterium represent an original vectorial model. Mycoplasma is a contagious pathogen which can be prevented by examinations during purchase of an animal. At least, regarding Bacillus and Nocardia, environnemental risks and feeding management are mandatory, but reservoirs are not easily identified. When it comes to treatment, it is important to note that either physical or chemical isolation during milking, or the culling of carriers is often the only profitable therapeutic option. [less ▲]
